Description
Technical Field
The invention relates to a fireproof coating, in particular to a novel inorganic expansion steel structure fireproof coating and a preparation method thereof, belonging to the field of fireproof coatings.
Background
The steel structure is widely applied to the field of buildings due to the characteristics of high strength, good toughness, good shock resistance, good extensibility and the like. The steel structure is a good thermal conductor, and the bearing capacity and temperature relationship of the steel structure shows that the bearing capacity can be rapidly reduced along with the increase of temperature, so that the fire resistance of the steel structure is poor. Experiments prove that when the temperature of the steel structure reaches about 550 ℃, the steel structure loses most of bearing capacity. When a fire disaster occurs, the temperature of a fire scene can reach about 1000 ℃, and at the temperature, the building collapses because the steel structure loses bearing capacity and deforms, so that a great amount of casualties and property loss are caused. In contrast, people usually adopt fire-proof methods such as concrete coating, thermal insulation partition coating, spraying after mixing mineral fibers and cement, and spraying of steel structure fire-proof paint to protect steel structures from fire and flame. Among them, the application of fire retardant coatings is the most direct, convenient, and effective method, and also has excellent decorativeness, thus being widely used.
The steel structure fire-retardant coating can be divided into an expansion type fire-retardant coating and a non-expansion type fire-retardant coating according to different fire-retardant mechanisms; can be divided into indoor and outdoor fireproof coatings according to the application range; according to different dispersion media, the coating can be divided into water-based fireproof coating and solvent-based fireproof coating; according to the difference of the coating thickness, the coating can be divided into thick (more than 7mm), thin (3-7 mm) and ultra-thin (less than 3mm) fireproof coatings.
The thick-coated fireproof coating for the steel structure mainly comprises inorganic fireproof coating, the coating is low in price, little in harmful gas release during flame retardance and environment-friendly, but the coating has the defects of large thickness, inconvenience in construction, insufficient bonding force, poor decoration and the like; the thin type expansion steel structure fireproof coating mainly adopts a water-soluble type, the thickness of a coating layer in construction is generally 3-7 mm, the decoration and physical and chemical properties are good, and an expansion layer formed by expansion foaming blocks steel and a fire source in a fire disaster to protect a building steel structure. The fire-retardant coating mostly uses an organic polymer base material as a binder, generates a large amount of harmful gas during flame retardance, and is not environment-friendly; the ultrathin steel structure fireproof coating has excellent bonding performance, excellent leveling performance and good decorative finish. The coating is ultra-thin and less than 3mm, the construction is convenient, and the coating is dried quickly. However, the existing ultrathin steel structure fireproof coating is mainly of an organic type, pollutes the environment in production and construction, releases a large amount of toxic smoke in flame retardance and is harmful to human health; in addition, the composite material has the defects of high price, poor weather resistance and aging resistance and the like, and is not in line with the future development trend of green environment-friendly materials.
Chinese patent CN 105885488A discloses a preparation method of a novel inorganic ultrathin expansion steel structure fireproof coating, liquid sodium silicate, expansion graphite, low-melting-point glass powder, magnesium hydroxide, latex powder and water are weighed according to a formula, the mixture is added into a stirrer to be stirred to enable the coating to be uniformly dispersed, and the mixture is canned for later use, the liquid sodium silicate is independently used as a binder in the patent, experiments prove that when the liquid sodium silicate is independently used, the curing time of the liquid sodium silicate is too long when the modulus is low, the water resistance is too poor, the curing time of the liquid sodium silicate is shortened along with the increase of the modulus, the water resistance is enhanced, but the expansibility is poor, wrinkles exist after the coating is formed into a film, the cracking is easy to occur after the combustion time is long, and the fireproof performance cannot meet the requirement; in addition, the use of magnesium hydroxide in large amounts in this patent can lead to cracking of the coating, poor coating expansion and reduced fire performance.
Therefore, aiming at the technical problems, the application provides a novel inorganic expansion steel structure fireproof coating and a preparation method thereof, and the fireproof material has the characteristics of high expansion layer strength, small smoke gas amount, excellent film forming and fireproof performance, low cost, simple preparation process, convenience in operation, environmental friendliness and the like.

Detailed Description
Preferred embodiments of the present invention are described in detail below.
Example 1: in this example, the film forming properties of liquid sodium silicate with modulus of 1.5, 2.0, 2.5, 3.0, and 3.3 were investigated to determine the effect of liquid sodium silicate alone on the film forming properties and fire-retardant properties of fire-retardant coatings, and the film forming properties of the samples are shown in table 1.
TABLE 1 Effect of liquid sodium silicate modulus on coating film Forming Properties
As can be seen from Table 1, when the low modulus liquid sodium silicate is used as a film forming agent, the curing time is longer, when the modulus is 1.5, the curing time is longer than 96h, the curing time is reduced along with the increase of the modulus of the liquid sodium silicate, when the modulus reaches more than 3.0, the curing time is only 2h, but because the high modulus sample is dried too fast, wrinkles can appear, the film is not formed, the film is easy to crack in the combustion process, once the fireproof coating is cracked, the purpose of fire prevention can not be achieved, and the lower the modulus is, the better the expansibility of the sample is.
The liquid sodium silicate samples with modulus of 2.0, 2.5, 3.0, 3.3 were tested for fire performance and the test results are shown in fig. 1.
According to the fireproof curve in fig. 1, curves a, b, c and d in the graph correspond to moduli of 2.0, 2.5, 3.0 and 3.3 respectively, and the temperature rising speed of the steel plate is increased and then reduced along with the increase of the modulus of the liquid sodium silicate within 20min of the test time, which is mainly because the water content in the system is high when the modulus of the liquid sodium silicate is smaller, the heat is absorbed in the temperature rising process, the void content in the coating is generated at the same time, the heat conduction coefficient of the coating is reduced, and the temperature rising speed of the steel plate is slowed down. However, in the later stage of testing, the final temperatures of the liquid sodium silicate samples with different modulus are stabilized at about 350 ℃, and the main reason is that the liquid sodium silicate samples with different modulus expand during fire prevention, and the expansion layer is attached to the steel plate to delay the heat transfer of flame, thereby achieving good fire prevention effect.
Fig. 2 is an appearance diagram before and after fire prevention of liquid sodium silicate formulas with different moduli, wherein e, f, g and h respectively correspond to the appearance diagrams after fire prevention of a, b, c and d.
As can be seen from fig. 2, liquid sodium silicate samples with different moduli all swell, but the low modulus sample has a more serious burn-through phenomenon, because the low modulus sample has a large swelling height, a thin swelling layer wall and a lower strength, and melts through under the violent impact of flame, and the swelling layer strength also increases with the increase of the modulus, but the swelling property is reduced, to sum up, the sample prepared by using liquid sodium silicate with the modulus of 3.0 as a single film-forming agent has a better performance, but the film-forming property and the fire-proof property still have problems, such as wrinkles on the surface of the sample, a lower swelling factor, and a yet to be improved fire-proof property.
Example 2: this example is the effect of the modulus of solid sodium silicate alone on the film forming properties of the coating: in an effort to prepare a pure solid phase coating, the film forming properties of solid sodium silicate having modulus of 1.0, 2.0, 2.5, 3.3 were studied and the film forming properties and appearance of the sample are shown in table 2 and fig. 3.
TABLE 2 influence of modulus of solid sodium silicate on film-forming properties of coatings
| Modulus of elasticity | 1.0 | 2.0 | 2.5 | 3.3 |
| Water consumption (solid-liquid ratio) | 1.7:1 | 1.7:1 | 1.7:1 | 1.7:1 |
| Number of cracks/(stripes/cm)2) | - | 0.6 | 0.8 | 0.8 |
| Crack length/cm | - | 0.7 | 1 | 1 |
| Crack width/cm | - | 0.1 | 0.1 | 0.2 |
| Curing conditions | ＞24h | About 2h | About 2h | About 2h |
As can be seen from table 2 and fig. 3, a, b, c and d in fig. 3 correspond to the moduli 1.0, 2.0, 2.5 and 3.3, respectively, and apart from the solid sodium silicate with the modulus of 1.0, when the solid sodium silicate with other moduli is made into a film forming agent, severe cracking phenomenon occurs, and the greater the modulus, the more significant the cracking phenomenon and the falling phenomenon of the sample occur, because the solubility of the solid sodium silicate in water decreases with the increasing modulus of the sodium silicate, and the modulus of 3.3 is only dissolved in hot water, while for the inorganic fireproof coating, the substance having a main binding effect is a sodium silicate solution, so the high modulus solid sodium silicate has poor binding property, and the sample cracking phenomenon is severe. The solid sodium silicate sample with the modulus of 1.0 has good cohesiveness, but has long hardening time, and the sample does not harden after 12 hours, so the solid sodium silicate is not suitable for independently forming a film to be used as the inorganic fireproof coating film-forming agent.
Example 3: in this embodiment, the influence of solid-liquid sodium silicate mixing ratio on the film forming property and the fire resistance of the fire-retardant coating is shown, but as can be seen from the embodiment 1 and the embodiment 2, when the liquid sodium silicate or the solid sodium silicate is used as a film forming agent alone, the sodium silicate is an ideal inorganic film forming agent, in order to optimize the film forming property and the fire resistance of the coating and reduce the water content as much as possible (cracking is caused by the volume shrinkage of a sample in the process of drying and water loss), according to the analysis of the above experimental results, the embodiment selects the liquid sodium silicate with modulus of 3.0 as the main component and a small amount of solid sodium silicate with modulus of 1.0 as the auxiliary component, uses the solid-liquid mixed sodium silicate as the film forming agent of the steel structure fire-retardant coating, and researches the film forming property and the fire resistance of the film forming agent with mass ratio of the solid-liquid sodium silicate of 0:40, as shown in table 3 and fig. 4.
TABLE 3 influence of film-forming agent of sodium silicate mixture on film-forming property of paint
| Mass ratio (solid: liquid) | 0:40 | 1:39 | 1:12 | 1:7 | 1:5 |
| Film formation conditions | Slightly wrinkled | Severe wrinkles | Slightly wrinkled | Smooth and flat | Smooth and flat |
| Curing conditions | 1h | 1.5h | 2h | 2h | 6h |
| Expansion factor | 9 | 9 | 10 | 11 | 13 |
As can be seen from table 3 and fig. 4, a, b, c, d and e in fig. 4 correspond to solid-liquid mass ratios of 0:40, 1:39, 1:12, 1:7 and 1:5 respectively, f, g, h, i and j in the figure correspond to appearance diagrams after fire prevention of a, b, c, d and e respectively, when solid sodium silicate is not added, the surface of the sample has a wrinkle phenomenon, the sample surface is gradually smooth along with the increase of the solid-liquid sodium silicate mass ratio, namely the addition of the solid sodium silicate is increased, the expansion multiple is increased, when the solid-liquid sodium silicate mass ratio is 1:7, the sample surface is smooth and flat, no wrinkle occurs, the film forming property is optimal, and the expansion layer is of a multilayer structure and has excellent fire prevention performance. The solid sodium silicate is added, so that the compounding of the solid sodium silicate and the solid sodium silicate is achieved, the advantages of film-forming property and expansibility of the sodium silicate with different moduli are combined more fully, the sample slurry is more suitable for smearing, the curing time is suitable, and an expansion layer with an excellent structure can be formed during fire prevention. When the mass ratio of the solid-liquid sodium silicate to the liquid-solid sodium silicate is higher than 1:7, although the film forming is good, the expansion layer of the low-modulus sodium silicate is seriously burnt through due to the gradual increase of the doping amount of the low-modulus sodium silicate, and the curing time of the coating is prolonged, so that the film forming and fire prevention are not facilitated.
The fireproof curve of different solid-liquid sodium silicate weight ratios in the graph 5 can be obtained, the fireproof performance of a sample is greatly improved along with the increase of the amount of added solid sodium silicate, the testing temperature of the sample is slowly increased to 350 ℃ in 60min when the solid sodium silicate is not added, the testing temperature of the sample is increased to 300 ℃ in 60min when the mass ratio of the low-modulus solid-liquid sodium silicate to the high-modulus solid-liquid sodium silicate is 1:7, the final temperature is reduced by about 50 ℃ compared with that of a sample without the solid sodium silicate, and the fireproof performance is more excellent. However, when the amount of the solid sodium silicate added is too high, the strength of the expansion layer is reduced to burn through, and the fire-retardant property is lowered.
Example 4: the embodiment is the influence of the mixing amount of the solid-liquid sodium silicate mixed film-forming agent on the performance of the fire-retardant coating
The influence of the amount of the film-forming agent on the film-forming property and the fire-retardant property of the fire-retardant coating is explored when the mass ratio of the solid sodium silicate to the liquid sodium silicate is 1:7, as shown in table 4 and fig. 6.
TABLE 4 influence of solid-liquid sodium silicate mixed film-forming agent mixing amount on coating film-forming property
| Mixing amount/ |
20 | 30 | 40 | 50 |
| Film formation conditions | Severe cracking | Is slightly rough | Smooth and flat | Smooth and flat |
| Curing conditions | 1h | 1.5h | 2h | 2h |
| Expansion factor | - | 3 | 10 | 13 |
As can be seen from table 4 and fig. 6, the amounts of a, b, c and d in fig. 6 correspond to 20, 30, 40 and 50, respectively, and when the amount of the film forming agent is 20 parts by weight, the amount of the film forming agent is less than 20 parts by weight, which is insufficient for the whole coating to bond, so that the sample has a severe cracking phenomenon, and the appearance of the coating tends to be good as the amount of the film forming agent is gradually increased, and experimental results show that the film forming can be satisfied when the amount of the film forming agent is more than 30 parts by weight.
The samples with the film forming agents of 30 parts by weight, 40 parts by weight and 50 parts by weight were subjected to the fire resistance test, and the test results are shown in fig. 7.
As can be seen from fig. 7, after the sample is subjected to a fire-proof test for 60min, the final temperature of the steel plate is firstly reduced and then increased along with the increase of the doping amount of the film forming agent, when the doping amount of the film forming agent is 30 parts by weight, the specific gravity of sodium silicate in the sample is less, the expansion performance is poorer than that of the sample with the doping amount of 40 parts by weight, so the fire-proof performance of the steel plate is poorer, when the doping amount of the film forming agent is 50 parts by weight, the sample has the worst fire-proof performance because the film forming agent accounts for over high total specific gravity of the coating, the strength of the expansion layer is lower, and the fire-through phenomenon is easy to occur during fire prevention, so the fire-proof performance of the steel plate is obviously reduced, when the doping amount of the film forming agent is.
Example 5: this example was conducted on 3 flame retardants with different foaming temperatures: al (OH)3About 200 ℃ and Mg (OH)2MgCO at about 350 deg.C3The influence of 500 ℃ or so on the fireproof performance of the paint was examined, and the results are shown in fig. 8 and 9.
As can be seen from FIG. 8, Al (OH)3The sample used as the foaming agent shows the best fireproof performance, when the steel plate is fireproof for 60min, the temperature of the back of the steel plate is about 280 ℃, and the expansion layer structure is a multilayer expansion structure, so the performance is the best. As is clear from FIG. 9, in FIG. 9, a, b, c and d respectively correspond to the side surfaces of aluminum hydroxide, magnesium carbonate and aluminum hydroxide, and Mg (OH)2The sample as blowing agent did not expand, MgCO3The sample used as the foaming agent was a large hollow foam and did not expand inside, and only Al (OH)3Samples as blowing agentsIs a multilayer expansion structure due to Al (OH)3The foaming temperature of (a) is consistent with the melting foaming temperature of the sodium silicate used by us.
Example 6: this example shows the effect of the aluminum hydroxide content on the film-forming and fire-proof properties of the paint: the results of the film forming property and the fire-proof property of the fire-retardant coating were investigated for the fire-retardant coatings with the aluminum hydroxide content (parts by weight) of 10 parts, 15 parts, 20 parts, 25 parts, 30 parts, 35 parts, 40 parts and 45 parts, respectively, and the results are shown in fig. 10 and 11, in which a, b, c, d, e, f, g and h in fig. 11 correspond to the content of 10, 15, 20, 25, 30, 35, 40 and 45, respectively.
As can be seen from FIG. 10, the fire-retardant property is according to Al (OH)3The mixing amount is increased, the strength is increased firstly and then the strength is weakened, and when the mixing amount is about 35%, the performance reaches the best; corresponding to FIG. 11, Al (OH)3When the amount of the additive is low, serious burn-through phenomenon occurs, and the burn-through phenomenon is improved along with the increase of the amount of the additive, because Al (OH)3The aluminum oxide is also an excellent inorganic filler while serving as a flame retardant, and the reaction product of the aluminum oxide is also a high-temperature resistant material, so that the fire resistance of the coating can be enhanced.
Example 7:
the feed comprises the following raw materials in parts by weight: 5 parts of solid sodium silicate by dry weight, 25 parts of liquid sodium silicate by dry weight, namely the solid-liquid ratio of the sodium silicate is 1:5, the modulus of the solid sodium silicate is 0.5, the modulus of the solid sodium silicate is 3, 20 parts of aluminum hydroxide, 10 parts of low-melting-point glass powder, 5 parts of magnesium oxide, 0 part of American Megaku HP8029 redispersible latex powder, 3 parts of organosilicon waterproofing agent, 0.6 part of tributyl phosphate and 10 parts of water;
is prepared by the following steps:

b. Accurately weighing liquid sodium silicate and tributyl phosphate according to the weight parts, adding water, and uniformly mixing and dispersing to obtain the component B.
c. And (3) placing the A, B component in the step into a stirrer, and uniformly mixing and dispersing to obtain the novel inorganic expansion steel structure fireproof coating.
The performance of the novel inorganic expansion steel structure fireproof coating prepared by the method is tested, and the process is as follows:
the prepared novel inorganic expansion steel structure fireproof coating is brushed on a steel plate (10mm multiplied by 1.5mm) at one time, the thickness of the coating layer is 2.9mm, the maintenance is carried out under the conditions that the humidity is 60% +/-5% and the temperature is about 25 ℃, and the fire resistance test is carried out after the standard maintenance for 14 days: the side coated with the fire retardant coating was placed on an alcohol burner flame 10cm from the flame, and the temperature of the other side of the steel plate was measured with a surface thermocouple and the temperature and time data was recorded.
